Fairmont Vancouver Airport Hotel's many restaurants have better food...

White Spot - at the Canadian domestic departures section (before security)
Most of the better restaurants are over at the Canadian domestic departures section.
FYI - the entire YVR airport is one big terminal. From Canadian domestic section to US departures section takes you 3 mins walking !
Fairmont Hotel is directly above US departures hall.

There really isn't anything decent to eat after security.
